Indeed, it's been a long and well-known fact that Zoroark's metabolisms are the stuff of legend. They had seemed to be able to stuff themselves with the same amount of food as a Snorlax and yet gained not a single pound.

Of course, since the entire species revealed they are, in fact, rather rotund, the theory of their having a sort of storage dimension for a stomach has been utterly dispelled.

The previously-mentioned clothing the species tend to wear for thorax support also proves as a gauge for when a Zoroark achieves parental status: when they've gained enough weight to the point that they tear through their bra, they begin to seek out a mate to start a family.
